When playing on Hard mode in later maps like Prometheus and Elysium, any long term base needs to made of Concrete or Limestone, or else you have to repair the external pieces after every expedition, since most operations trigger high tier storms. I had one sitting with 4 t6 storms in 3 hours.

Personally, I don't like the look of concrete compared to, say, scoria brick or even beeswax building materials, but I also don't want to repair them every time I return to base.

The solution? Weatherproof coating.

This could come in two tiers: weatherproof coating and hardend weatherproof coating.

Weatherproof coating: crafted at the machining bench for some combination of epoxy, organic resin, and paint, this item can be attached to any placeable building piece to increase its storm resistance by one tier permanently, persistent after the piece is picked up. One piece of coating covers one building piece.

Hardened weatherproof coating: Crafted at the chemistry station with some combination of polymers, compounds, and epoxy, this acts just like the above coating except it gives 2 tiers of resistance.

Now your scoria brick building can survive t7 storms!
